﻿/**  
*本日历选择控件由tiannet根据前人经验完善而得。大部分代码来自meizz的日历控件。  
*tiannet添加了时间选择功能、select,object标签隐藏功能，还有其它小功能。  
*使用方法：  
* (1)只选择日期 <input type="text" name="date" readOnly onClick="setDay(this);">  
* (2)选择日期和小时 <input type="text" name="dateh" readOnly onClick="setDayH(this);">  
* (3)选择日期和小时及分钟 <input type="text" name="datehm" readOnly onClick="setDayHM(this);">  
*设置参数的方法  
* (1)设置日期分隔符 setDateSplit(strSplit);默认为"-"  
* (2)设置日期与时间之间的分隔符 setDateTimeSplit(strSplit);默认为" "  
* (3)设置时间分隔符 setTimeSplit(strSplit);默认为":"  
* (4)设置(1),(2),(3)中的分隔符 setSplit(strDateSplit,strDateTimeSplit,strTimeSplit);  
* (5)设置开始和结束年份 setYearPeriod(intDateBeg,intDateEnd)  
*说明：  
* 默认返回的日期时间格式如同：2005-02-02 08:08
